If a deaf person's hearing aids are ringing or whistling loudly and the person does not seem to know, should you tell them, or is that rude?
I would rather be told than not. Of course it's nice if the person can be somewhat discreet about it. If my aid is whistling when my husband and I are out with friends, he knows to get my attention and make a little motion by his ear to clue me in.
So I take it you cannot hear the squealing?
I'm very sensitive about it and the feedback I get from hugs makes me cringe. If I weren't so short, I wouldn't end up with my ear pressed to other peoples chests.
